Description

Technical Field

[0001] The invention relates to the technical field of liquid crystal television structures, in particular to an ultra-high definition television back panel. Background Art

[0002] The LCD screen uses liquid crystal material as the basic component. The liquid crystal material is filled between two parallel plates. Voltage is used to change the arrangement of the molecules inside the liquid crystal material to achieve the purpose of light shielding and light transmission to display images of varying depths and staggered patterns. In addition, as long as a filter layer of three primary colors is added between the two plates, color images can be displayed. LCD screens have very low power consumption, so they are favored by engineers and are suitable for electronic devices using batteries. The TV back panel is an important support mechanism for the entire device.

[0003] Referring to the Chinese invention patent, the publication number is: CN 112930087 B, and the name is: An ultra-high-definition television back panel, including an inner back panel and an outer back panel; the inner back panel is a hollow structure, and the periphery of the inner back panel is fixed to the face frame; the top edge, left edge and right edge of the outer back panel all protrude forward, and are respectively fixed to the top edge, left edge and right edge of the inner back panel, and a frame is provided between the bottom edge of the outer back panel and the bottom edge of the inner back panel; a plurality of heat dissipation holes are provided on the frame, and a heat dissipation fan connected to a television controller is provided at the inner end of the heat dissipation hole, and a heat dissipation pipe with a built-in inverted whisker is screwed into the heat dissipation hole. The present invention discharges heat to the outside through the heat dissipation fan, and the heat dissipation pipe with a built-in inverted whisker can effectively reduce the entry of lint into the interior of the television. However, there are still some problems in actual use: When installing the TV, you still choose to hang it on the wall or place it on the table in the traditional way. When hanging it on the wall, a support frame is required. When changing the installation method, the support frame needs to be removed. The TV back panel is easily damaged during the disassembly process, and the TV body is easily damaged due to improper operation, which seriously increases the difficulty and risk of replacement. Secondly, when choosing to place the TV, the support foot is the only fulcrum of the TV body, and its stability directly affects the stability of the TV placement. Summary of the invention

[0004] Technical issues solved The purpose of the present invention is to make up for the deficiencies of the prior art and provide an ultra-high-definition television back panel.

[0014] Beneficial effects: Compared with the prior art, the ultra-high-definition TV back panel has the following beneficial effects: 1. The present invention provides an installation adjustment mechanism, and uses a tool to rotate the hexagon socket screw to rotate the main bevel gear. At this time, the driving rod is driven to rotate by the meshing action of the transmission main gear, and then the sleeve ring is driven by the thread to move the clamping strip from the inside of the connecting groove to the inside of the connecting cover. At the same time, the limit strips slide close to each other. During this process, the connecting support frame rotates with the driving rod until its bottom end is vertical to the back panel body, which is conducive to simplifying the installation method of the TV back panel. When switching between hanging and placing, there is no need to disassemble the connection structure too much, thereby ensuring the stability of various connection methods and enhancing practicality.

[0015] 2. The present invention provides an adjustable limiting mechanism. When the mounting support frame and the back panel body are in a vertical state, the bottom end of the limiting strip moves to the inside of the limiting groove. At this time, the adjusting head is rotated to rotate inside the connecting hole. When magnet one rotates to the same cross-section of the connecting hole, the magnetic attraction of magnet one and magnet two on opposite sides is opposite. Then magnet two pulls the reset spring to extend and pass through the limiting hole at the same time until the poles of magnet one and magnet two attract each other and are close to each other. Next, the adjusting head is rotated in the opposite direction to make the poles of magnet one and magnet two the same. At this time, the poles repel each other. At the same time, the reset spring reacts to reset magnet two through the limiting hole to the inside of the connecting hole. At the same time, the limit of the limiting strip is released, which is beneficial to ensure that the mounting support frame cannot move when the TV is placed, thereby ensuring the stability of the TV placement method.

[0016] 3. The present invention provides a protective mechanism to press the control rod to push the base backward. At this time, the extrusion spring contracts and the adjustment strip contracts to the opposite side. At this time, the limit rod contracts toward the inside of the mounting support frame, releasing the limiting operation on the contact strip. Subsequently, one end of the contact strip is pulled up and flipped backward so that it is on the same horizontal line as the rear end of the mounting support frame, and then slides backward until the inside of the contact strip wraps the rear end of the mounting support frame, thereby facilitating the placement of the TV to increase the contact area and maintain stability with the placement surface.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] like Figure 1-9 As shown, the present invention provides a technical solution: an ultra-high-definition television back panel, comprising a back panel body 1, a group of left-right symmetrical connecting grooves 2 are fixedly connected to the rear end of the back panel body 1, a mounting support frame 3 is arranged on the rear side of the connecting groove 2, the mounting support frame 3 is in an H shape, and the front ends of the mounting support frame 3 are movably connected to the inside of the connecting groove 2 through bearings, an installation mode adjustment mechanism 4 is movably connected to the opposite sides of the connecting groove 2, both sides of the bottom end of the mounting support frame 3 are movably connected to a protective mechanism 5, a group of left-right symmetrical limit grooves 6 are opened in the middle position of the mounting support frame 3, and the relative device of the limit groove 6 can adjust the limit mechanism 7.

[0022] like Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, the installation mode adjustment mechanism 4 includes a driving rod 401, a transmission bevel gear 402, a main bevel gear 403, a hexagon socket screw 404 and a collar 405. The collar 405 is provided with two and is symmetrically connected to the outside of the driving rod 401. The transmission bevel gear 402 is fixedly connected to the middle position of the driving rod 401, the main bevel gear 403 is located directly above the transmission gear, and the main bevel gear 403 is meshed with the transmission bevel gear 402. The hexagon socket screw 404 is fixedly connected to the axis of the main bevel gear 403. A group of left-right symmetrical threads are provided on the outside of the driving rod 401, and the collar 405 is slidably connected to the driving rod 401 through threads. Both ends of the driving rod 401 pass through the connecting groove 2 and are fixedly connected to the opposite side of the connecting shaft of the mounting support frame 3. The installation mode adjustment mechanism 4 also includes a clamping strip 406, a limit strip 407 and a connecting strip. The cover 408 and the limit strip 407 are respectively fixedly connected to the outer side of the bottom end of the ring 405, and the limit strip 407 is respectively fixedly connected to the top of the limit strip 407, the connecting cover 408 is fixedly connected to the rear side of the back plate body 1, and a connecting groove 2 is provided at the bottom of the connecting cover 408. The driving rod 401, the transmission bevel gear 402, the main bevel gear 403, the ring 405, the clamping strip 406 and the limit strip 407 are all located inside the connecting cover 408. The bottom end of the limit strip 407 passes through the connecting groove 2 and extends to the outside of the connecting cover 408. The bottom end of the hexagon socket screw 404 passes through the connecting cover 408 and extends to the top thereof. A moving groove 8 is provided on the opposite side of the connecting groove 2, and the moving groove 8 and the clamping strip 406 are located in the same cross section. The moving groove 8 is adapted to the end of the clamping strip 406 away from the ring 405, and a limiting hole 11 is provided at the bottom end of the limit strip 407.

[0023] By turning the hexagon socket screw 404 with a tool, the main bevel gear 403 rotates. At this time, the driving rod 401 is driven to rotate by the meshing transmission main gear, and then the sleeve ring 405 is driven by the thread to drive the clamping strip 406 so that the inside of the connecting groove 2 moves to the inside of the connecting cover 408. At the same time, the limit strips 407 slide close to each other. During this process, the connecting support frame rotates with the driving rod 401 until its bottom end is vertical to the back panel body 1, which is conducive to simplifying the installation method of the TV back panel. There is no need to disassemble the connection structure too much when switching between hanging and placing, thereby ensuring the stability of various connection methods while enhancing practicality.

[0024] like Figure 1 , Figure 2 , Figure 4 , Figure 8 and Fig. 9As shown, the adjustable limiting mechanism 7 includes an adjusting head 701, a connecting shaft 702, a magnet 1 703, a magnet 2 704 and a reset spring 705. The connecting shaft 702 is fixedly connected to the axis of the adjusting head 701. Four magnets 1 703 are arranged in a ring shape and fixedly connected to the outer side of the connecting shaft 702. The reset spring 705 is symmetrically arranged. The magnet 2 704 is respectively fixedly connected to one end of the reset spring 705 on the opposite side. A mounting hole 9 is provided on the opposite side of the limiting groove 6. The end of the connecting shaft 702 away from the adjusting head 701 passes through the mounting support frame 3 and is movably connected to The inside of the mounting hole 9, and the connection between the connecting shaft 702 and the mounting support frame 3 are all movably connected through bearings. The mounting support frame 3 is provided with a group of left-right symmetrical connecting holes, and the connecting holes are axially symmetrically arranged with the connecting shaft 702 as the symmetry axis. The end of the reset spring 705 away from the magnet two 704 is fixedly connected to the inside of the connecting hole. The magnet one 703 is axially symmetrical with the poles consistent in pairs, and the poles of the two adjacent magnets one 703 are opposite, and the poles on the opposite sides of the magnet two 704 are arranged consistently. When the poles of the magnet one 703 and the magnet two 704 attract each other, the suction force is greater than the pulling force of the reset spring 705.

[0025] When the mounting support frame 3 is in a vertical state with the back panel body 1, the bottom end of the limit strip 407 moves to the inside of the limit slot 6. At this time, the adjusting head 701 is rotated to make it rotate inside the connecting hole. When magnet one is rotated to the same cross section of the connecting hole, the magnetic attraction of magnet one and magnet two on opposite sides is opposite. Then magnet two pulls the reset spring 705 to extend and pass through the limit hole 11 at the same time until the poles of magnet one and magnet two attract each other and are close to each other. Then, the adjusting head 701 is rotated in the opposite direction to make the poles of magnet one and magnet two the same. At this time, the poles repel each other. At the same time, the reset spring 705 reacts to magnet two 704 to reset to the inside of the connecting hole through the limit hole 11. At the same time, the limit of the limit strip 407 is released, which is beneficial to ensure that the mounting support frame 3 cannot move when the TV is placed, thereby ensuring the stability of the TV placement method.

[0026] As shown in FIG. X, the protection mechanism 5 includes a contact strip 501, a control rod 502, a limit rod 503, an adjustment strip 504, a base 505 and a squeeze spring 506. The adjustment strip 504 is in an outward-facing shape and is movably connected to one side of the base 505 through a torque spring and a rotating shaft, and the squeeze spring 506 is fixedly connected to the side of the base 505 away from the adjustment strip 504. The control rod 502 is fixedly connected to the center of the base 505, and the control rod 502 is located on the opposite side of the adjustment strip 504. The limit rods 503 are respectively fixedly connected to the top of the adjustment strip 504, and the squeeze spring 506 is fixedly connected to the bottom of the base 505. The spring 506, base 505, adjustment, control rod 502 and limit rod 503 are all located inside the bottom end of the mounting support frame 3, and the control rod 502 and the limit rod 503 both penetrate the mounting support frame 3 and extend to its outside. The reset spring 705 is fixedly connected to the bottom end of the mounting support frame 3. Slide grooves 10 are provided on both sides of the contact strip 501. The inner width of the contact strip 501 is consistent with the rear end width of the mounting support frame 3. The contact strip 501 is movably connected to the two sides of the rear end of the mounting support frame 3 through the slide grooves 10, and the limit rod 503 is adapted to the limit hole 11.

[0027] When the mounting support frame 3 is detached from the wall, the control rod 502 is pressed to push the base 505 backwards. At this time, the extrusion spring 506 contracts and the adjustment strip 504 contracts to the opposite side. At this time, the limit rod 503 contracts toward the inside of the mounting support frame 3, releasing the limiting operation on the contact strip 501. Then, one end of the contact strip 501 is pulled up and flipped backwards so that it is on the same horizontal line as the rear end of the mounting support frame 3, and then slides backwards until the rear end of the mounting support frame 3 is wrapped inside the contact strip 501, which is beneficial for increasing the contact area and maintaining stability with the placement surface when the TV is placed.

[0028] Working principle: When it is necessary to change the TV installation method, use a tool to turn the hexagon socket screw 404 to rotate the main bevel gear 403. At this time, the driving rod 401 is driven to rotate by the meshing transmission main gear, and then the sleeve ring 405 is driven by the thread to drive the clamping strip 406 so that the inside of the connecting groove 2 moves to the inside of the connecting cover 408. At the same time, the limit strips 407 slide close to each other. During this process, the connecting support frame rotates with the driving rod 401 until its bottom end is vertical to the back panel body 1. When the installation support frame 3 is detached from the wall, the control rod 502 is pressed to push the base 505 backwards. At this time, the extrusion spring 506 contracts, and the adjustment strip 504 contracts to the opposite side. At this time, the limit rod 503 contracts toward the inside of the installation support frame 3, releasing the limiting operation on the contact strip 501, and then the contact strip 501 is pulled up. The end is flipped backward so that it is on the same horizontal line as the rear end of the mounting support frame 3, and then slides backward until the contact strip 501 wraps the rear end of the mounting support frame 3. When the mounting support frame 3 is in a vertical state with the back panel body 1, the bottom end of the limit strip 407 moves to the inside of the limit slot 6. At this time, the adjusting head 701 is rotated to make it rotate inside the connecting hole. When magnet one is rotated to the same cross-section of the connecting hole, the magnetic attraction of magnet one and magnet two on opposite sides is opposite. Then magnet two pulls the reset spring 705 to extend and pass through the limit hole 11 at the same time until the poles of magnet one and magnet two attract each other and are close to each other. Next, the adjusting head 701 is rotated in the opposite direction so that the poles of magnet one and magnet two are the same. At this time, the poles repel each other. At the same time, the reset spring 705 reacts to magnet two 704 to reset to the inside of the connecting hole through the limit hole 11, and at the same time, the limit of the limit strip 407 is released.
